Lenovo ThinkPad Tablet vs. Apple iPad 2

We didn't intend for the iPad 2 (shown right) to be pictured displaying a comic book, but it's a fitting counterpoint to the ThinkPad Tablet's more business-minded approach to its tablet features, which include McAfee security and Citrix desktop virtualization.

The bottom edge of the ThinkPad Tablet offers (left to right) a dock connection for an optional charging base; a Micro-USB port; a Mini-HDMI port; and a headphone jack. A cover on the far left conceals a full-size SD card slot, along with an optional 3G SIM card slot.

Another detail you'll notice about the ThinkPad Tablet is that it looks as if someone drilled a hole into its side. Lenovo has smartly integrated a cubbyhole into the side of the tablet for holding an optional digital pen accessory. What's more, there are holes in both the pen and the tablet that allow you to attach the pricey pen ($39.99) for safekeeping. It's the best design we've seen yet for those who need regular access to a pen digitizer. If you don't plan on using the ThinkPad Tablet with a stylus, Lenovo includes a plastic cover that plugs the hole.
